HEATING MEGHAN ISM FOR PRESSE S.

Application filed July 18,

T 0 all whom it may concern Be it known that We, CHARLES L. BRALEY and GEORGE N. LINK, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improve:

ments in Heating Mechanism for Presses, of which the following is a specification.

This invention relates to small presses utilized in laundry work and more particular such devices as cuff, neck-band, and yoke presses.

These small presses as a rule consist of two ironing members or heated platens one of which is fixed and the other of which is movable toward and from the fixed member in two directions 2'. 6. it is movable laterally out of alinement with a stationary member so that the article may be applied to it and then moved into alinement after which this movable member is brought into contact with the stationary member for pressing pressure. In another type of these presses the movable member is limited to movementin alinement with the stationary member and it does not have a lateral movement into and out of alinement with the stationary member but a work support is utilized and this work support is movable into and out of alinement with the pressing members and it receives the article and carries it back into alining position. In all of these presses where a movable member is heated or where heat is to be supplied on both sides of the article to be treated, it is necessary to provide swinging or yielding joints in the pipes where the steam or such heating medium is used. While these swinging or yielding joints are effective so far as the operation of the press is concerned they are nevertheless a bad feature and a troublesome factor in that they leak and become loose and interfere with the perfect operation of the machine. The present invention therefore is designed to overcome this disadvantage and provide a stationary heating member which is in close contact with the movable member so that the heat of this heating member is radiated or transmitted directly to the movable member.

The invention will be further set forth in the following description, drawings, and claims.

Referring to the drawings Figure 1 is a Specification of Letters Patent.

side elevation of the headof the machine with parts broken away and shown insection; Fig. 2 is a section upon the line 2-2 of Fig. 1; 3-3 of Fig. 1, and Fig. 4'is "asection of a portion of the machine taken upon the line 44 Fig. 1 one halfof the machine being broken away.

In the form shown 1 represents a suitable frame to which are secured arms- 2 of the stationary pressure member 3 which is provided with a heating chamber 4. This member 3 is provided with a- V shaped pressing surface 5 utilized in pressing cuffs and of a construction thoroughly familiar to those skilled in the art. is provided with an inlet pipe 6 for steam or other heating medium, and'thispipe communicates with the chamber '4. The member 3 is also provided at the lower end of each of the side portions or legs with discharge pipe connections 7.

Extending upward from the lower part of the machine, which is not shown but is of the usual construction, is a reciprocating rod 8 having mounted thereon a head 9 adapted to receive an intermediatemember 10 which supports the movable ironing member. This movable ironing -member comprises a frame portion 11 open at the, sides and merginginto a cylindrical shank 12 at substantially the center of the machine and forming a part of the ironing web 15 is provided with a transversely dis-v posed recess 16 for receiving a sliding rod 17, secured in the support as will appear. The hollow plunger 14 is I provided with hollow radially extending arms 18 passing out through the side openings in the frame portion 11 and secured to'the arms 2 of are.

Fig. 3 is a section on the line The member 3 the stationary member by suitable bolts 19 r so that the laterally extending arms 18 of the plunger 14 are fixed to the stationary ironing member.

The hollow shank 12 fits nicely about the plunger so that when the latter is heated,

heat is transmitted to the movable ironing member. Rotation about the plunger, of the movable ironing member is prevented by the engagement of the rod 17 in the recess 16.

Each of the arms 18 as shown in Fig. 4i is connected to a pipe 20 and these pipes to gether with the pipes 7 are connected to the two lines 21 and 22 forming a return of the steam circulating system. Upon the upper surface of the movable member 13 is a plate 23- provided with a suitable padding 24 and secured to a front plate 25 in which is mounted the rod 17, the projected end of this rod being threaded to receive a handle 26. In use it willbe seen that when steam is supplied to the machine the stationary ironing member is heated and the movable ironing member is heated through the medium of the plunger and the hollow shank or cylinder 12. Inthis way all swinging joints or flexible connections in pipes are avoided. The press operates in a manner similar to all of the smaller presses of this type utilized in the laundry industry.

Having describedour invention we claim 1. Ironing, apparatus, com-prising cooperating ironing members between. which the work is ironed, one of said members being movable toward and from the other to produce the ironing efiect, a stationary heating member for heating the movable ironing member, and means for supplying'heating medium to the heating member.

2. The combination with an ironing member of an ironing apparatus, of a stationary heating member, said ironing member being movable relative to said heating member, said members being so arranged as to be in heat radiating relation at all times, and means for supplying heating medium to said heating member.

3. Ironing apparatus, comprising a frame, a stationary ironing member carried thereby, a cooperating ironing member movable toward and fromsaid stationary member to producethe ironing effect, a heating member in heat transmitting relation with the movable ironing member and stationary with respect thereto, and fixed means for supply ing heat to the heating member.

4:. Ironing apparatus, comprising a. frame, a stationary ironing member carried thereby, a movable ironing member mounted in said' frame and having a heat receiving and conducting portion forming a guide, a stationary heating member mounted in the frame and engaging said guide, and means for supplying heat to the heating member.

5. Ironing apparatus, comprising a frame, a stationary ironing member, a movable ironing member having a cylindrical portion, a heating member having a plunger portion engaging in said cylindrical portion, means for supplying heat to said plunger portion, and means for preventing rotation of the movable ironing member with respect to .the heating member.

6. Ironing apparatus, comprising a frame, a. stationary ironing member, a movable ironing member having a cylindrical portion, a heating member having a plunger portion engaging in said cylindrical portion, means for supplying heat to said plunger portion, and means for preventing rotation of the movable ironing member with res sect to said plunger, said means comprising a rod extending through the cylindrical por tion and engaging in a recess in the plunger portion.

7. A pressing machine, comprising a. hol

low frame having a pressing surface and a heat radiating portion immovable relative to each other, means for circulating heating medium through said frame for heating said surface and radiating portion, and a pressing member heated by said radiating portion and movable relative to said pressing surface.

8. A pressing machine, comprising opposed hollow members one of which is provided with a pressing surface and the other with a heat radiating portion, and a pressing member movable back and forth from member to member.

9. A pressing machine, comprising opposed hollow members one of which is provided with a pressing surface and the other with a heat radiating portion, and a pressing member movable back and forth from member to member and adapted to be heated by said radiating portion and to cooperate with said pres-sing surface.

' 10. Xrprcssing machine, comprising a hollow frame having an open central portion forming opposed connected pressing and heat radiating members, and a pressing member movable in saidspace from one of said members to the other.

11. A pressing machine, comprising a hollow frame havin an open central portion forming opposed connected pressing and heat radiating members, said heat radiating member haw ing a portion extending into said space, and a pressing member movable in said space from one of said members to the other.
